BRUSH-MAKING MACHINE.

Specification of Letters Patent. Patented J 11119 29, 1915.

Application filed November 24, 1913. Serial No. 802,682.

To all whom it may concern Be it known that I, CoxnAn J o'BsT, a citi- Z'en of Germany, and a resident of Toledo, in the county of Lucas and State of Ohio, United States of America, have invented a certain new and useful Brush-Making Machine; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to brush making machines, and particularly to machines of this class of the compound type, or those adapted to both drill and fill brush backs.

.points on a brush-back, whereby a boring of holes oran anchoring of bristletufts of uniform depth therein is accomplished.

A further object of the invention is the provision of means which not only accurately accomplishes a boring of holes of uniform depth and a uniform anchoring of bristle-tufts therein, but which also provides a than-anvil or abutment for acting against the brush-back carrying member to oppose each boring or bristle-tuft setting operation, thus improving on the action of machines of this class.

A further object of my invention is the provision of an improved mechanism having a plurality of separate work carrying parts which are operable to have corresponding compound oscillatory movements in unison to repeatedly place work carried thereby in different predetermined erated on.

A further ob ect of the invention is the positions to be opprovision of simple and efficient means which, during a running of the machine, is automatically operable to intermittently lock and release the pattern-wheels to hold them rigid during the drilling and filling operations or either.

Further objects and advantages will be apparent by reference to the following detailed description.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a-preferred embodiment thereof is illustrated in the accompanying,

drawings, in which,

Figure 1 is a left side elevation ofa machine embodying the invention. Fig. 2 is a front elevation thereof. with parts broken away, and with the drilling, filler and other parts removed. Fig. 3is a right side elevation of the machine. Fig. 4 is a top plan view thereof with parts broken away. Figs. 5, 6 and 6 are details of the master Wheel locking mechanism and parts thereof. Figs. 7 and 8 are enlarged side elevations of the brush-back carrying mechanisms, with parts broken away and with the mechanism in Fig. 8 tilted from horizontal position. Figs. 9 and l0are top plan views of such mechanisms and associated parts with the brushcarrying member thereof in different positions of its horizontal swinging movements. Fig. 11 is a sectional detail of a portion of the brush-carrying member-of said mechanism and associated control parts. Figs. 12,

13 and Marc face and different sectional views of the cam thrust plate of said mechanism. Fig. 15 is an enlarged sectional detail of portions of said mechanism, and Fig. 16"

is an edge view of a brush after having its bristle-tufts set in position by the machine.

Referring to the drawings, 1' designates the. portion of the machine frame which carries the parts and mechanisms embody.- ing the features of my invention and which is shown as being substantially 'U-shap e, and- :2 the frame part which is disposed in front of the part- 1 at one side thereofand has the table part 2 extending laterally from the left side of its top, said part 22 carrying V the drilling and filler mechanisms of the machine, both of which mechanisms are commonly usedin machines of this class and which, in themselves, contain no patentable nates ahead or chuck for carrying a and 4 the filler nozzle, such drill head and I nozzle, in the present instance, being horizontally spaced, as best shown in Fig.4.

Mounted for forward and backward movements on the top of the frame'l over the crotch or open portion thereof is a table.

5, which is provided near its forward end with an elongated longitudinally-extending opening 5 and has its side edges working 1n suitable guide-ways in the frame sides. Bearings 6, 6 are fixedly carried by the table 5 at opposite sidesof the opening 5 with their shaft receiving openings in axial reg ister, and j ournaled in these forfree rocking movements is-a hollow shaft 7, which-extends transversely'of-the frame-and preferably stands in substantially the horizontal plane of the drill-head 3 and fi'ller4. The shaft 7, at each end thereof withoutthe bearings 6, 6 fixedly carries a forwardlyprojecting U-shaped rocker-head or .yoke

member 8, and-from the portion of the shaft Y intermediate the bearings 6, 6 forwardly projects an arm 9. The shaft 7 and parts 8 and i -9 are preferably cast in a single piece, but

may be formed in any other suitable manner as desired. I I

Ea'ch rocker-head or yoke member 8 has the inner sides of its legs in spaced parallel relation, and mounted therebetween is a brush-back carrying-frame 10, which has its Y upper and lower sides parallel to the inner sides of theyoke legs and loosely mounted therebetween' for horizontal swinging and longitudinal sliding movements relative thereto. A. pivotstud' 11 projects upward and 'downward from. the respective upper and lower sides of each frame 10, preferably near the front or outer end thereof, and into an associated bearing-block or bar 12, which is of elongated form and mounted for reciprocatory movements in a' longitudinally disposed slot 13 inthe adjacent rocker-head leg. It is thus evident that the frame 10 is peri mitted-to have forward and backward sliding movements relative to the rocker-heads by which it is carried, and also to horizontally turn at any point of such movement with the studs 11' as its axis. A coiled-compression spring 11 connects the outer end of each pivot Stud 11 with a stud 15 or other fixed part on the inner end portion of the respective leg of the associated rocker-head and serves-to urge the frame 10 inward toward the inner or closed end of the rocker-head. The front or outer end of each frame 10 is provided at itsinner side witha thrust plate 16, the purpose of which will be hereinafter. more fully described, and at the outer side of such plate it carries a pair of brush-back clampin blocks 17-17 which are disposed in superimposed relation, and

have their side edges slidingly embracing screw 21 has hearings inthe upper and .the shaft 7 and fixedly attached rocker- .thereof in opposition. to the trolscrew 21, which projectsfdown Iiithe.

rearof the-blocks and hasdifie'rent portions 5' in right and left thresfadid engagementlwith registering portions 0 t e respective blocks,

as shown at 22 in Fig. 7. The stem of the:

lower front edge portions of the-frame 10, as at 23, and is anchored in any suitable manner. against longitudinal movements relative'to the frame.

A master-wheel 24 loosely mounted within the opening of the frame part 1 ona 35 shaft 25 therein, and fixed to the sides thereof are the pattern cam-wheels 26 .and- 27, the former of which determines the vertical tilting or oscillatory movements of y heads or yoke members 8, 8, while the latter determines the horizontalv swin move- .ments of the frames 10, 1Q,"relative to the yoke members. Coiiperatingwith the camwheel .26 to control the rocking'movements of the shaft 7 is a slide 28,- which is suitably mounted within the frame part 1 for'vertical reciprocatory movements over the shaft 25 and at the sideof the cam wheel 26 and carries a stud or roll 29' at one side thereof for riding upon the periphery of the. cam

,wheel 26, whereby reciprocatory movements are imparted to the slide in accordance with the cam formation of the wheel periphery.

The slide 28 is provided 'at its upper end with a head portion 28, the top side of,

which forms a horizontally-elongated surface upon which rides a roll 30 that is car-- ried by the arm 9 at one. side of its free'end. It is thus evident'that the vertical move ments ofthe slide 28 will communicate pre- I determined rocking movements to the'shaft 7 and the parts carried thereby.

The cam periphery of the pattern wheel 27 coacts with a roll or stud 31 which projects from the side of a vertically movable slide'member 32 and rides on ,saidwheel at the top side thereof. See Fig. 2.) The slide member 32 is suitably guided for vertical reciprocatory movements .by the frame 1 and has a finger 33 projecting from a side Heel 2?. A bell crank lever 31 is fulcrumed for vertical rocking movements to aL-bracket-arm 35 projecting from theleft side of the frame 1, and this lever has one arm projecting upwardly and carrying, in the ipresent in stance, an anti-friction roll 36 and its other arm projecting horizontally with the free end portion thereof extending into a verend of an axially shiftable shaft 39, which shaft extends loosely through the hollow of the -shaft 7. The shaft 39 is yieldingly urgedto cause the plate 38 to constantly bearinward against the lever roll 36 by the attachingpf aiweighted cable 40' to the opposite end of the shaft, which cable passes outwardly from the shaft end over a sheave 41' and carries aweight 42- at its free or loose end, or such urging action may be accomplished in any other suitable or convenient manner, The sheave 41 is shown as beingcarried by an arm 43 projecting rearwardly' from the adjacent side portion of the frame part 2 Y Aathrust-rod or finger 44 is carried by the shaft 39 at each. end thereof. in substantial parallelism therewith, one" rod pro- .jecting inwardly from the upper portion of the plate 38- and. preferably having a pin point bearing against the inn'er'end of the adjacent brush-back carrying frame 10 Y within a bearing depression 45 therein, as

best shown in Figs. 7 to 11, while the other rod'orfingr ia-projects inwardly from an arm 46 onthe shaft 39 and has its free end in {similar pin-point bearing against the inner end. of the adjacent frame 10. A coiled contractile,spring ,47- connects the inner end of each frame 10 to the adjacent part 38,1 16 and serves to yieldingly retain the respective frame end and thrust rod 39 in bearingcontact. -The rods or fingers it, Jet-are carried for limited pivotal movements' the parts 38, .46 to permit the frames 10 to have'sliding'movements relative to the rocker heads 8, 8. It is thus evident that an axial movement of the shaft 39 in one direction will cause one of the thrust fingers 4% to push against the asso-. 'ci-ate'd frame 10 and the spring 47 at the opposite end of the shaft 39 to have a pulling action on the other frame 10 to swing the frames in-unison, and that a movement of .the shaft 39 in the opposite direction will cause the other of said thrust fingers H and springs -17 to act against the respective frames to swing the same in the opposite direction relative to the carrying heads'or yoke members 8. The connection between the shaft 39 and frames 1O, 10 is the forward end portion of the table 5 is an arm 49, which projects within the forward end portion of the adjacent brush-- back carrying frame 10 and has a finger 5O projecting forward from its free end and ,in constant end-thrust contact with the sitionto the, drill head 3 and filler 4, as the case may be, and to serve as an anvil or firm abutment for resisting the -rearward pressure which is'exerted on an associated brushback during the respective drilling and filling operations. Inasmuch as the axis of the shaft 7 and the anvil or abutment members 4950 are in constant spaced relation during an operation of the machine, a vertical swinging ofthe rocker-heads 8 and frames 10 from horizontal positions will permit the frames 10 to move inward under the influence of the springs 11. a sufficient distance to compensate for the difference in the lengths of the radii between the swinging axis of the rocker-heads 8, 8 and difi'erentpoints on the surface of the brush-back at which thedrilling or filling operation occurs, thus placingeach point of a brush-back, as it moves into register with the drill or filler, in proper relation thereto for the drilling or filling operation. In other words, the disthe anvil roll 52 permits the frame 10 to' move inward under the influence of the springs la a sufficient distance to compensate for the difference in'length of theradii, as shown by the position of the parts in Fig. 8.

The purpose of the cam surface 53 on each plate 16 is to cotipera'te with the anvil roll 52 to gage the depth of the drilling and filling movements of the drill-and filler, respectively, when the brush-back carrying parts are tilted from horizontal position, or the frame 10 is swung from its straight ahead position so that the depth of the holes which are drilled in a brush-back, and the depth of anchoring of the bristle tufts therein, will tance between the swinging axis ofa rocker:

be uniform throughout the area of the brush- 139 g anzoi-itwardl backto the;edges:tliereof,'the incline of the "loose' belt-pulley and anaxially movable gagement with the pulley 55 to cause a yielding of the shaft fromsuchpulley. A shipper ever 57 is fulcrumed to the frame part 2, as at'58, and has a part in shifting 5 engagement with the hub portion of 'the' clutch member 56. The free end. of this" lever is connected by a link 59 to a crankarm 60 on a shaft 61, which is journaled in the frame part 2 transversely of the shaft 5d and has-an arm- 62 projecting horizontally therefrom and attached to a vertically-disposed treadle-rod 63. This rod is guided for reciprocatory movements and has its lower end provided with a foot-pressure receiving 35 part 64. A coiled contractile spring65 connects an ear 66 on the'rod;63 to a fixed part of the frame, as at 67-, and cooperates with such' rod, the bell-crank lever 60-61-62 and lever 57 .to normally hold the clutch member "56 out of clutch engagement with therfiulley 55.

e clutch member 56 is retainedin env gagement vith its member 55 against the tension of thespring 65 by the engagement of a catch-finger 68, which is'pivoted to the frame part 2, as at 69,-with a pin or lug 70 projecting upward.- from the link 59, as shown in Figs. 2, and 3. ihoriz' ntally-dis} posed bar 71 is pivotally EonneEtedtdthe hand-control lever 72 that is fulcrumed to the frame 2, as at'73,' and has its free "end connected to a -r0d,'74, which in turn com. nects at its other end to an arm? 5 on a. rock 55 shaft 7 6. The rock-shaft'76 is v jonrnaled in suitable bearings at the rear sid'eJ'of the frame part land has an arm 77 depending vtherefrom in position for its lower end to be engaged at each revolution of the 'wheel to,- rock such arm.

A11 adjusting of the screws,100 and 10-1 relative to the lever 95 will permit the pawl to have a stroke of greater or less length, as it may be desired to move the ratchet-wheel a distance equal to one or more teeth at each impulse.

' Carried by the bracket 99 at one side i thereof at the rear of the ratchet-wheel 24:

is a box or housing 106 in which a wheel locking detent 10? is mounted for rec1procatory movements in a radial direction relative to the, wheel. A spring 108 acts to urge the nose end of the detent into a registering periphery recess of the wheel. A'trip-finger 109 hangs from the pivot of the pawl for free movements relative thereto and has its freeend working down through anopening 110 in the box 106 at one side of the detent,

and is provided on the side thereof adjacent to said detent with a lip or projection 111 having correspondingly inclined upper and lower sides. A stud or pin 112 projects from the side of the detent 107 in registerwith the lip 111, and such lip, upon a downward movement of the finger 109, coacts with the pin to. force the detent 10? rearward from wheel locking position. and, upon an upward movement of said finger, coa'cts with said pin to swing the finger rearward to permit it to rise without disturbing the locking position of the detent. It is thus evident that the 'detent 10? remains in locking engagement with the wheel 24 to prevent a movement of the same in either direction exceptv during the down or wheel moving stroke of the pawl 97.

. 113 designates; a push-rod which extends rearward through a guide opening in the left side portion'of the frame 1. and has its rear end provided with a finger 114 which extends upward in advance of the and detent 107 in substantially flush rela tion to the side ofthe ratchet-wheel 24:,

whereby a rearward movement 'of the rod 113 will .causethe finger. 11 i to engage the nose ends of said pawl and detent and move the same from engagement with the Wheel teeth.

Fixed to the outer side of the pattern wheel or cam 26 in concentric relation to the wheel 21 is a bevel-gear 115 with which a, drive pinion 116 -meshes. The pinion 116 is carried by a shaft 117, which is journaled in suitable bearings 118 and 119 attached to the'frame parts'l and 2, respectively, and

has its forward end provided with a handwheel-120 that is disposed in convenient reach of the operator. The purpose of this hand drive for the ratchet-wheel 24 is to enable such wheel to be turned backward or forward a predetermined distance to permit the refilling of one or more holes in a brush-back with bristle-tufts in case of improper feeding of bristle-tufts in the first instance. It is evident that when the rod 113 has been moved to release the pawl 97 and detent 107 from engagement with 'the ratchet-wheel 24, the hand driving n echas;

also .clamps abored brush-back, which is designated 20*, to the carrying frame 10 disposed at the rear of the filler nozzle 4, the back 20 having been'bored during a previous cycle of operations of the machine. This having been done, the operator depresses the foot-controllederod 63 to force the clutch member 56 into engagement with the pulley 55 against the tension of the spring 65, the parts being held in such clutch engaging position by the catch-finger 68, which is moved into catch engagement with the pin 70 of the link 59 of the clutch shifting mechanism, the finger 68 being urged into. the pin engaging position shown in Fig. 3 by the actionof the spring 9 on the handcontrolled lever 72. At each complete rotation of the shaft 5-1, the rod 85, which forms a part. of the-connection between the lever 86 and crank-wheelSO, moves said lever to a movement equal to the width of one tooth of the wheel or equal to the width of more than one tooth, as it may be desired to bore the holes in the blank 20 and to place the bristle-tufts in the back 20 a greater or less distance. apart. As the. wiieel 24 rotates, the brush-back carrying frames 10, 10 .are automatically swung in vertical and hori- 'zont-al directions to move the brush-backs P 70 i'p i -t r ingf hole i oneFZndthefiIlingf holes 111 the other, in 'prgiPerIy, spaced irelation throughout the area; of thebacks, such" movements .of the frames-being controlled-{bythe or patr lr i 'h ls an 27 n dem s m echa- 2S upward'a gains't the ;roll 30 .on the .the horizontalffmovements of the 4 a nesia relative tmthe rocker-heads 8 are "eifectedbyflaxial movements of the shes-a9,
